If they haven't moved they're located somewhere around Allentown, Pa. Been around for at least 7-8 years. The 99% claim is legit, but not for me. I've seen (not done) a rep draw a 70# bow (no arrow) aim it at the ground and slowly remove his hand from the grip. The weight of the ow is enough to keep it at full draw. Just don't wiggle the string or you'll have aluminum braces in your teeth.

The one thing people must consider about this. Like any high letoff bow people are looking for a solid wall to hold against. The reason for the solid wall is that most bows do not have enough holding weight to be able to aim solidly. So they have to pull againstwall or draw stop to, in effect, raise the holding weight to maybe 20#. The same is true for the Concept bows.
